Description
Technical field
The invention belongs to organic chemical industry field, more particularly to a kind of preparation method of octane number accelerating agent.
Background technology
In recent years, highlighting with home and abroad environment problem, countries in the world start the stringenter gasoline mark of strict implement
Standard, improves gasoline quality, solves the problem of environmental pollution that the use of fossil fuel is brought.In the used many metals of people and
In nonmetallic octane rating promoter, the using effect of metallic anti-knock agent is splendid and additive amount is small.But the shortcomings that it is maximum is discharge
Heavy metal, has high risks to environment so that it has dispute in use, and long-time service is also bound to cause Metal-accumulation, draws
Play spark plug failure, cause the defects of exhaust valve lost of life.For this reason, people put into great effort again studies pure organic compound
As octane rating promoter, such as methyl tertiary butyl ether(MTBE) (MTBE), it is with preferable anti-knock properties, but its oxygen content is higher,
Additive amount is larger (generally higher than 10%) in gasoline harmonic process, and octane number lifting is ineffective；It is easier to penetrate into ground at the same time
Lower water source, and water pollution is caused, therefore its use is subject to certain restrictions and restricts.
Therefore, pollution-free, stable processing technique, safe, the obvious octane of octane number enhancing rate how is prepared
Value accelerating agent is current wide concerned technical problem.
